Splitting Team During Warm Up - Technical?

[NCHSAA]

Red Team is already warming up prior to the game. The locker room door is positioned just off of the baseline, and in line with the sideline extended. As the Blue Team comes out to run the length of the court to their side, half run down the sideline, while the other half run 3 to 4 feet deep of the baseline and down the other side line. They never step onto the court, or interfere with Red Team's warmup.

Technical or not? I cannot find the citation.

Thanks!
